As you can see on the profile of Sarah Seabolt there is no documentation to support claims that she was Cherokee. The Seabolts are found in numerous contemporaneous records as white; Abraham appears on 1830 and 1831 lists of white men with permits to live in the Cherokee Nation with a wife and three children, on an 1834 census of the free white population of Lumpkin County with a family of ten, and on the 1838 census of Lumpkin County with a family of 12.
You might check out the Flower Name Study; not my study. In my family, the Flower/Flowers surname are one and the same. I have a Flowers line in NYS.
